Well you can’t but it digitally at all anymore and if you do find the disc it’s usually priced as a “retro collectible” so the only reasonable way to get it is via the high seas—which, technically, is “really cheap”
Honestly if it’s a game where the difficulty is structured around teaching you a skill then the the devs response is actually kinda on point (while also funny). It’s like someone submitting a complaint that the piano is too difficult and the skill bar should be lowered so that they shouldn’t have to just practice and learn to play like everybody else. But I could be wrong (I usually am)
